STAVANGER, Norway -- Statoil Petroleum, operator of production license
035, is in the process of concluding the drilling of wildcat well
30/11-12 S and appraisal well 30/11-12 A. The wells were drilled 2 km
south of the 30/11-9 A (Askja Øst) discovery, and about 35 km southwest
of the Oseberg Sør facility in the North Sea.
The objective of well 30/11-12 S was to prove petroleum in three sandstone layers in Middle
Jurassic reservoir rocks (Tarbert formation). The objective of well
30/11-12 A was to delineate in the event a discovery was made in well
30/11-12 S. The 30/11-12 S well encountered a 37-m oil column in the
upper part of the Tarbert formation, of which about 30 m had good to
moderate reservoir properties. Well 30/11-12 A, which was drilled
further down on the structure, encountered similar reservoir rocks, but
is dry.

Preliminary
estimates place the size of the discovery at between 0.7 and 2.5 million
standard cubic metres of recoverable oil equivalents. The discovery
will be included in the evaluation of a new field development, along
with other earlier discoveries in the area. Data has been collected and
samples have been taken in both wells.
Both wells were drilled to
vertical and TDs of 3,669 m and 3,671 m, respectively, and 3,609 m and
4,144 m below the sea surface. Well 30/11-12 S was terminated in the
Ness formation and 30/11-12 A bottomed in the Tarbert formation. The
wells are the 12th and 13th exploration wells in production license 035,
which was awarded in 1969.
Water depth is 110 m. The wells have
been permanently plugged and abandoned. Both wells were drilled by the
Songa Delta drilling facility, which will continue its drilling campaign
with the drilling of another wildcat well (30/11-13 S) in the same
production license, where Statoil is the operator.
